5 Input Specifications and External wiring
5.6 Input Interruption (I00 to I50 ) - With Delay Function
5.6 Input Interruption (I00 to I50 ) - With Delay Function
The PLC (main unit) is provided with an input interruption function (input delay interruption function) and has
six interruption input points.
The ON or OFF duration of interruption input signals should be 5
µ
s or more.
1.
Allocation of pointers to input numbers (input signal ON/OFF duration)
→
For details on programming, refer to the programming manual.
→
For the wiring, refer to Section 7.3.
2. Input interruption delay function
This input interruption has a function to delay execution of interruption routine in 1ms units.
With this delay function, the position of the sensor used for input interruption can be adjusted in the sequence
program. It is necessary to adjust the actual position of the sensor.
→
For the programming, refer to the programming manual.
3. Non-overlap of input numbers
The input terminals X000 to X007 can be used for high-speed counter, input interruption, pulse catch, SPD,
ZRN, DSZR and DVIT instructions and general-purpose inputs.
Take care not to overlap the input numbers.
Example:
When the input interrupt pointer "I001" is used, X000 is occupied. Therefore, it is impossible to use C235,
C241, C244, C246, C247, C249, C252 and C254, input interruption (including delay interruption) pointer I000,
pulse catch contact M8170 and SPD, ZRN, DSZR and DVIT instructions at the same time.
